Red Flag #: Abdominal Pain And Tenderness
Early on, there may be no noticeable symptoms that melanoma has spread to the liver. When symptoms do show up, they commonly include an enlarged, hard, or tender liver and pain in the upper right area of your abdomen, just below your ribs. Other signs cancer has spread to the liver are similar to symptoms of liver disease: fluid buildup in the belly and yellowing of the skin and eyes .
What Are The Risk Factors For Melanoma
Some of the risk factors for melanoma are:
- Presence of a large number of moles and changes in the moles high risk
- Presence of atypical moles
The symptoms of melanoma vary between individuals. A new mole or a noticeable change in an old mole should be considered as a warning sign to undergo further testing.
The ABCDEF acronym is used to clinically identify a melanoma.
A Asymmetry of a mole
B Irregularity of the borders of the mole
C Color difference in the mole : Moles that change in color, become darker or show multiple colors should be suspected for the presence of melanoma
D Diameter of the mole. Melanoma usually occurs in moles with a diameter of more than 6 mm
E Evolving mole. A cancerous mole will show changes in height and width
F Feeling around the mole. There may be a change in sensation around the mole.
Testing For Gene Changes
For some people with melanoma, biopsy samples may be tested to see if the cells have mutations in certain genes, such as the BRAF gene. About half of melanomas have BRAF mutations. Some drugs used to treat advanced melanomas are only likely to work if the cells have BRAF mutations , so this test is important in helping to determine treatment options. Tests for changes in other genes, such as C-KIT, might be done as well.
A newer lab test known as looks at certain gene expression patterns in melanoma cells to help show if early-stage melanomas are likely to spread. This might be used to help determine treatment options. To learn more, see Whats New in Melanoma Skin Cancer Research?

Medical History And Physical Exam
Usually the first step your doctor takes is to ask about your symptoms, such as when the mark on the skin first appeared, if it has changed in size or appearance, and if it has been painful, itchy, or bleeding. You may also be asked about your possible risk factors for melanoma skin cancer, such as your history of tanning and sunburns, and if you or anyone in your family has had melanoma or other skin cancers.
During the physical exam, your doctor will note the size, shape, color, and texture of the area in question, and whether it is bleeding, oozing, or crusting. The rest of your body may be checked for moles and other spots that could be related to skin cancer .
The doctor may also feel the lymph nodes under the skin in the neck, underarm, or groin near the abnormal area. When melanoma spreads, it often goes to nearby lymph nodes first, making them larger.
If you are being seen by your primary doctor and melanoma is suspected, you may be referred to a dermatologist, a doctor who specializes in skin diseases, who will look at the area more closely.
Along with a standard physical exam, many dermatologists use a technique called dermoscopy to see spots on the skin more clearly. The doctor uses a dermatoscope, which is a special magnifying lens and light source held near the skin. Sometimes a thin layer of alcohol or oil is used with this instrument. The doctor may take a digital photo of the spot.
How Do You Diagnose Melanoma
For the initial diagnosis, a suspicious mole is examined with an instrument called the dermatoscope that is like a magnifying glass. Malignant melanoma is assessed by a biopsy. The entire lesion mole should ideally be removed with an adequate margin during biopsy.
Melanomas are also classified based on the degree of invasion with the higher stages determining a greater degree of invasion. Stages I and II have a good survival rate while those with melanoma stage IIB or higher have a poor survival rate.
Additionally, liver function tests and a chest x-ray are obtained to detect any spread of the melanoma.

Positron Emission Tomography Scan
A PET scan can help show if the cancer has spread to lymph nodes or other parts of the body. It is most useful in people with more advanced stages of melanoma.
For this test, you are injected with a slightly radioactive form of sugar, which collects mainly in cancer cells. A special camera is then used to create a picture of areas of radioactivity in the body.
PET/CT scan: Many centers have special machines that do both a PET and CT scan at the same time . This lets the doctor compare areas of higher radioactivity on the PET scan with the more detailed appearance of that area on the CT scan.
How Do You Assess Skin Cancer
To diagnose skin cancer, your doctor may:

How Is Melanoma Diagnosed
If you have a mole or other spot that looks suspicious, your doctor may remove it and look at it under the microscope to see if it contains cancer cells. This is called a biopsy.
After your doctor receives the skin biopsy results showing evidence of melanoma cells, the next step is to determine if the melanoma has spread. This is called staging. Once diagnosed, melanoma will be categorized based on several factors, such as how deeply it has spread and its appearance under the microscope. Tumor thickness is the most important characteristic in predicting outcomes.
Melanomas are grouped into the following stages:
- Stage 0 : The melanoma is only in the top layer of skin .
- Stage I: Low-risk primary melanoma with no evidence of spread. This stage is generally curable with surgery.
- Stage II: Features are present that indicate higher risk of recurrence, but there is no evidence of spread.
- Stage III: The melanoma has spread to nearby lymph nodes or nearby skin.
- Stage IV: The melanoma has spread to more distant lymph nodes or skin or has spread to internal organs.
If You Need Surgery For A Biopsy
Did your doctor say you need an operation to check your lymph nodes? In that case, youâll probably first get an injection of a radioactive substance or dye to show the lymph nodes closest to your tumor.
The surgery is usually done in a hospital, and you can go home after it. During the procedure, the doctor makes a small cut — about a half-inch — and takes out one or more lymph nodes closest to your melanoma.
If those nodes contain melanoma cells, the cancer has likely spread. But if the sentinel lymph nodes show no melanoma cells, then the doctor will leave your lymph nodes alone.

Can You Prevent Melanoma
The best way to prevent all kinds of skin cancer, including melanoma, is to protect yourself whenever you are out in the sun.
- Try to stay out of the sun during the middle of the day .
- Wear sun-protective clothes when you are outside, such as a hat that shades your face, a long-sleeved shirt, and long pants.
- Use sunscreen every day. Your sunscreen should have an SPF of least 30. Look for a sunscreen that protects against both types of UV radiation in the sun’s raysâUVA and UVB. When you are outdoors for long periods of time, reapply sunscreen every 2 hours.
- Take extra care to protect your skin when you’re near water, at higher elevations, or in tropical climates.
- Avoid sunbathing and tanning salons.
Check your skin every month for odd marks, moles, or sores that will not heal. Check all of your skin, but pay extra attention to areas that get a lot of sun, such as your hands, arms, and back. Ask your doctor to check your skin during regular physical examinations or at least once a year.
Metastatic And Recurrent Melanoma
Melanoma can spread to other parts of the body, where it can cause tumours. When melanoma has spread and appears as a tumour in another part of the body, it sometimes can be successfully treated with surgery. But metastatic melanoma usually needs other treatments, too, such as chemotherapy, interferon, immunotherapy, or radiation therapy.
Metastatic melanoma and melanoma that can’t be removed with surgery may be treated with inhibitors.
Melanoma can come back after treatment. This is called recurrent melanoma. All of the treatments mentioned above may be used for recurrent melanoma as well as:
- Hyperthermic isolated limb perfusion. If the melanoma is on your arm or leg, chemotherapy medicine may be added to a warm solution and injected into the bloodstream of that arm or leg. The flow of blood to and from that limb is stopped for a short time so the medicine can go right to the tumour.
- Medicines injected directly into the tumour.
- Lasers to destroy the tumour.
If your melanoma can’t be cured, your doctors will try to control symptoms, reduce complications, and keep you comfortable.
Your doctor may recommend that you join a clinical trial if one is available in your area. Clinical trials may offer the best treatment option for people who have metastatic cancer. Clinical trials study other treatments, such as combinations of chemotherapy, vaccines, and immunotherapies. They are also studying targeted therapy.

Sentinel Lymph Node Biopsy
If melanoma has been diagnosed and has any concerning features , a sentinel lymph node biopsy is often done to see if the cancer has spread to nearby lymph nodes, which in turn might affect treatment options. This test can be used to find the lymph nodes that are likely to be the first place the melanoma would go if it has spread. These lymph nodes are called sentinel nodes .
To find the sentinel lymph node , a doctor injects a small amount of a radioactive substance into the area of the melanoma. After giving the substance time to travel to the lymph node areas near the tumor, a special camera is used to see if it collects in one or more sentinel lymph nodes. Once the radioactive area has been marked, the patient is taken for surgery, and a blue dye is injected in the same place the radioactive substance was injected. A small incision is then made in the marked area, and the lymph nodes are then checked to find which one became radioactive and turned blue. These sentinel nodes are removed and looked at under a microscope.
If there are no melanoma cells in the sentinel nodes, no more lymph node surgery is needed because it is very unlikely the melanoma would have spread beyond this point. If melanoma cells are found in the sentinel node, the remaining lymph nodes in this area are typically removed and looked at as well. This is known as a lymph node dissection .
Stress Hair Loss And Body Image
- The diagnosis of melanoma and the need for treatment can be very stressful. You may be able to reduce your stress by expressing your feelings to others. Learning relaxation techniques may also help reduce your stress.
- Hair loss can be emotionally distressing. Not all chemotherapy medicines cause hair loss. And some people have only mild thinning that is noticeable only to them. Talk to your doctor about whether hair loss is an expected side effect with the medicines you will receive.
- Your feelings about your body may change following a diagnosis of melanoma and the need for treatment. Adapt to your body-image changes by talking openly about your concerns with your partner and discussing your feelings with your doctor. Your doctor may also be able to refer you to groups that can offer more support and information.
Having cancer can change your life in many ways. For help in managing these changes, see the topic Getting Support When You Have Cancer.

Red Flag #: Headaches Or Visual Changes
Just like the liver, not everyone will notice symptoms of melanoma spreading to the brain. But when symptoms do show up, its usually in the form of headaches, problems with eyesight, paralysis on one side of the body, or seizures. If someone simply has a headache, that doesnt mean they have advanced stage melanoma, Dr. Yushak says. But if its a headache thats not going away after a week, and you never have headaches, then thats something that definitely needs to be checked out.
What Are The Signs Of Melanoma
Knowing how to spot melanoma is important because early melanomas are highly treatable. Melanoma can appear as moles, scaly patches, open sores or raised bumps.
Use the American Academy of Dermatology’s “ABCDE” memory device to learn the warning signs that a spot on your skin may be melanoma:
- Asymmetry: One half does not match the other half.
- Border: The edges are not smooth.
- Color: The color is mottled and uneven, with shades of brown, black, gray, red or white.
- Diameter: The spot is greater than the tip of a pencil eraser .
- Evolving: The spot is new or changing in size, shape or color.
Some melanomas don’t fit the ABCDE rule, so tell your doctor about any sores that won’t go away, unusual bumps or rashes or changes in your skin or in any existing moles.
Another tool to recognize melanoma is the ugly duckling sign. If one of your moles looks different from the others, its the ugly duckling and should be seen by a dermatologist.

How Is Melanoma Treated
The type of treatment you receive depends on the following:
-
How deeply the melanoma has grown into your skin
-
Whether the cancer has spread to another part of your body
-
Your overall health
Your dermatologist, oncologist , or oncology team will consider the above when creating your treatment plan, which may include one or more of the following treatments.
Surgery: When treating melanoma, doctors strive to remove all the cancer. Because surgery tends to be the most effective way to do this, a patient who has melanoma will often have surgery.
The type of surgical removal you receive depends largely on the type of melanoma you have, where its located, and how deeply it goes. If you have an early melanoma, your dermatologist may treat it with one of the following procedures, which can be performed in a medical office while you remain awake.
If surgery can remove the cancer, this may be your only treatment. This is often the case with an early melanoma.
When melanoma grows deeper into the skin or spreads, treatment becomes more complex. Surgery may be part of your treatment plan, but other treatments will be used as well to help kill cancer cells. Some are given before surgery to shrink the cancer. Others are given after surgery to kill any remaining cancer cells.
The other types of treatment for melanoma are:

How Nodular Melanoma Is Diagnosed
Nodular melanoma is a fast-growing, aggressive form of skin cancer that presents as a firm, raised lesion on the skin. It may first be noticed during a self-skin check at home, or during an annual skin check by your dermatologist or healthcare provider.
If nodular melanoma is suspected, your healthcare provider will take a full medical history, perform an examination of the skin, and take a skin biopsy to reach a diagnosis.
Depending on whether or not the nodular melanoma has spread, other tests, such as an X-ray and MRI, may be necessary.
This article will review how nodular melanoma is diagnosed.
How Do Dermatologists Diagnose Melanoma
When you see a board-certified dermatologist, your dermatologist will:
-
Examine your skin carefully
-
Ask questions about your health, medications, and symptoms
-
Want to know if melanoma runs in your family
If any spot on your skin looks like skin cancer, your dermatologist will first numb the area and then remove all of it. This can be done during an office visit and is called a skin biopsy. This is a simple procedure, which a dermatologist can quickly, safely, and easily perform.
Having a skin biopsy is the only way to know for sure whether you have skin cancer.
The tissue that your dermatologist removes will be sent to a lab, where a doctor, such as a dermatopathologist, will examine it under a high-powered microscope. The doctor is looking for cancer cells.
What this doctor sees while looking at your tissue will be explained in the pathology report, including whether cancer cells were seen. If melanoma cells are seen, the report will include many important details, including:
-
The type of melanoma
-
How deeply the melanoma tumor has grown into the skin
-
How quickly the melanoma cells are growing and dividing
If its possible to tell the stage of the melanoma, the report will include this information.
Stages of melanoma
Heres an explanation of what each stage of melanoma means:
Stages of melanoma
Stage 0
The melanoma has spread to either: One or more nearby lymph node Nearby skin
Once the stage is known, the next step is treatment.
